Switch signs for M and N in the EllBase interface so that it now solves

  L\phi + M\phi + N\phi = 0
(in line with BAM_Elliptic).

 \item{\bf generic:} solves a linear elliptic equation by passing the 
 	stencil functions. There is support for a maximum of 27 stencil 
 	functions ($3^3$). {\em This is not implemented, yet}
